Abstract

An objective providing at least two fields of view and/or of surveillance from a single sighting axis dividing into two channels over one of which two magnifications and different fields can be obtained. The objective comprises a set (31) of at least one lens centered on a common optical axis (41) and, behind this set, with respect to the direction of propagation of the light, a reflector element (5). A movable component (61) constituted by at least one lens is movable between, on the one hand, a position between the set (31) of lenses and the reflector element (5) so as to be centered on the common optical axis, and, on the other hand, a position located after the reflector element (5) so as to be centered on the optical axis (43) symmetrical with the common optical axis (41) with respect to the reflecting surface of the reflector element (5). An instrument for viewing and/or surveillance, such as a periscope, can be equipped with this objective.
